DESCRIPTION
The Digital Motherboard is mounted near the center of the digital chassis as shown in Figure 8-1.
It has connectors on both sides to allow modules to be plugged into the front and rear of the digital
chassis. The motherboard has a total of eighteen card slots as shown in Figure 5-2, but slots 8 and 16
are not used for modules. Slot 8 has a special connector used when two PLC-TT I/O modules are
plugged into the rear of the chassis as shown in Figure 5-3. When viewed from the front of the chassis,
the two connectors on the extreme left are for the main and redundant power supplies. The two
corresponding connectors at the rear are for the power supply I/Os. At the rear of the chassis on the
right side is a JP40 connector, which is used for expansion power.
